BACKGROUND OF THE INVENTION

The present invention relates to video gaming systems and, moreparticularly, to improvements in a Video gaming machine that permit aplurality of players to simultaneously participate in a game.

Many video gaming machines are configured for single players. Forexample, a video blackjack or poker game machine may have one playerstation from which a player participates in an independent game executedby the machine's game processor. While popular, such games do notprovide the group interaction found in live casino games.

Moreover, single player games are often located in establishmentsfrequented by groups of customers and thus may be unattractive tocustomers not wishing to separate from their companions.

Video gaming machines typically include a cabinet housing at least aplayer station, a game processor assembly and a video monitor. Theplayer station includes at least one input device by which a playerinputs commands to the game processor. Generally these input devices arepush-buttons that, when depressed and/or released, trigger switches thatsend a signal to the game processor. However, any suitable input device,for example a joystick or touch screen, may be utilized. The playerstation also typically includes a currency acceptor by which a playerdeposits coins or paper currency for betting or for paying a fee to playthe game. The currency acceptor is often, but not necessarily, locatedproximate the input devices.

The game processor assembly is, generally, a computing assembly thatincludes an integrated circuit computing device that executes a videogaming program responsively to the commands input by the player at theplayer station. Often, this processor is a device, for example anerasable programmable read only memory (EPROM) which is customprogrammed to execute only the video gaming program or relatedfunctions. The EPROM is a “chip” mounted on a custom built circuit boardthat may include various peripheral devices as needed or desired. Thecircuit board is constructed specifically to operate in conjunction withthe video gaming machine and is typically capable of receiving the inputsignals directly from each input device. That is, a communication linedirectly links a single push-button to the circuit board.

Multiplayer video games are known which utilize custom circuitry such asEPROM arrangements. Due to its expense, however, custom circuitry may beimpractical for game developers working in early development stages.Thus, some gaming programs are initially developed on conventionalpersonal computers. These devices employ components such as a centralprocessing unit (CPU), memory, and an input/output system. The CPU is anintegrated circuit “chip.” It is a processor device that can perform amultitude of operations. It is not a single-program device but, instead,executes programs stored in memory by a user. The input/output systemmanages data handling among the CPU and other internal or externalcomponents.

Because it is a multipurpose device, the personal computer assemblytypically has no permanent input or output device having directcommunication to the main circuit board. Instead, data is conveyedbetween input and output devices and the input/output system via dataports. These ports may have predetermined uses, for example to receiveinput from a keyboard or a mouse or to direct output to a printer ormonitor. Personal computers also typically include expansion slots foradditional circuit boards which may include their own data ports.

For example, computer software games are known which dedicate certainkeys on a keyboard to individual players. However, a keyboard isinadequate for a video gaming machine, for example because of itsphysical awkwardness, because it would detract from game realism, andbecause it has no mechanism to receive currency for wagers or game fees.

Video gaming machines employing personal computer components without theaddition of custom circuit boards or ports include means for conveyingplayer input data to the CPU through existing components. For example, acurrency acceptor may output data to the main circuit board via anexisting serial port. However, multiplayer games include a relativelygreater number of input devices such as push-buttons and, consequently,a correspondingly greater number of communication lines than requiredfor a single player game. Because the existing input ports in a typicalpersonal computer configuration are inadequate to directly accommodatethese communication lines, an interface system is required to coordinatedata transfer between the player stations and the data port(s).

For example, multiplayer interactive video gaming machines are knownthat employ a network arrangement. Players play individual games fromindividual player stations, each having a keypad, a personal computercircuit board, and a monitor. Input from the keypad switches is conveyedto the player station circuit board, which executes the individualplayer blackjack game responsively to this input data and data relatingto the dealers hand provided by a central file server computer. Howeverthe multiple circuit boards contribute significantly to the costs ofsuch a configuration, while the heat generated by the CPUs contributesto increased maintenance costs.

SUMMARY OF THE INVENTION

The present invention recognizes and addresses the foregoingdisadvantages, and others of prior art construction and methods.

Accordingly, it is an object of the present invention to provide animproved multiplayer interactive video gaming device having a pluralityof independent player stations and utilizing personal computer hardware.

More particularly, it is an object of the present invention to providesuch a gaming device incorporating an improved interface assembly.

It is also an object of the present invention to provide an improvedinterface assembly that may communicate with the game processor via aninput port of the personal computer assembly.

It is still another object of the present invention to provide amultiplayer interactive video gaming device which simulates a livecasino game.

Some of these objects are achieved by a multiplayer interactive videogaming device including a plurality of independent player stations. Eachof the player stations includes at least one data input deviceconfigured to output a player input signal responsive to playeractivation. An interface assembly is in operative communication withmore than one of the player stations and includes an interface processordevice The interface processor device is configured to receive theplayer input signals and to output interface signals corresponding toparticular data input devices.

The gaming device also includes a personal computer assembly incommunication with the interface assembly such that the interfaceassembly connects the more than one player stations with the personalcomputer assembly. The personal computer assembly includes aninput/output system, at least one data input port, and a game processordevice. The game processor device is configured to receive, via the datainput port and the input/output system, data carried by the interfacesignals, to execute a video card gaming program responsively to theinterface signal data, and to output video display signals responsivelyto the video card gaming program.

A video display assembly in communication with the personal computerassembly is configured to receive video display signals and to displayvideo images responsively thereto.

In one preferred embodiment, three player stations communicate with oneinterface assembly. Each player station includes a plurality ofswitches. When depressed and/or released, each switch communicates aplayer input signal to an interface processor, a CPU forming a part ofthe interface device. The CPU, in turn, correlates the player inputsignal to a predetermined interface signal depending upon the switchfrom which the player input signal was received. The interface signal isthen stored in a buffer. It is retrieved by a game CPU on the personalcomputer main circuit board via the personal computer keyboard port andbasic input/output system (BIOS).

The CPU on the main circuit board executes the video gaming programresponsively to information input by players through the individualplayer stations and outputs video display signals to a monitor viewableby all the players.

In another preferred embodiment of the present invention, each playerstation includes a currency acceptor configured to accept currencywagers from the player at the player station and to output a signalcorresponding to the accepted currency amount to the main circuit boardCPU via the interface device. Alternatively, data lines may be providedfrom the currency acceptors directly to data input ports to the maincircuit board.

In still another preferred embodiment, a central ticket dispenser ismounted on the game cabinet within reach of all the player stations. Aplayer that has accumulated winnings may input a command from the playerstation to clear the accumulated winnings maintained by the card gamingprogram and to output a ticket reflecting these winnings. The ticket maybe redeemable for example, by the establishment owner. A printer incommunication with the main circuit board CPU is housed by the cabinetto print the tickets for output through the dispenser.

The cabinet may be constructed to provide a player portion thatsimulates a live casino card game table. The player portion has asemicircular shape, a foot rail, an arm rail, and drink holders disposedat each player station. Such a configuration adds to the realism of thegame and to the group atmosphere.

The accompanying drawings, which are incorporated and constitute a partof the specification, illustrate one embodiment of the invention and,together with the description serve to explain the principles of theinvention.

A full and enabling disclosure of the present invention, including thebest mode thereof, directed to one of ordinary skill in the art, is setforth in the specification, which makes reference to the appendeddrawings, in which:

FIG. 1 is a perspective view of a preferred embodiment of a multiplayerinteractive video gaming device constructed in accordance with thepresent invention; and

FIG. 2 is a schematic diagram of a preferred embodiment of a multiplayerinteractive video gaming device constructed in accordance with thepresent invention.

Repeat use of reference characters in the present specification anddrawings is intended to represent same or analogous features or elementsof the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the presently preferredembodiments of the invention, one or more examples of which areillustrated in the accompanying drawings. Each example is provided byway of explanation of the invention, not limitation of the invention. Infact, it will be apparent to those skilled in the art that modificationsand variations can be made in the present invention without departingfrom the scope or spirit thereof. For instance, features illustrated ordescribed as part of one embodiment may be used on another embodiment toyield a still further embodiment. Thus, it is intended that the presentinvention covers such modifications and variations as come within thescope of the appended claims and their equivalents.

The present invention is concerned with an improved multiplayerinteractive video gaming device. Accordingly, FIG. 1 depicts a presentlypreferred embodiment of a multiplayer interactive video gaming device,indicated generally at 10. A cabinet A is divided into a player portion12 and a display portion 14. Display portion 14 and player portion 12are attached by a connection piece (not visible in the view shown)through which communication and power lines may be passed.

Player portion 12 is constructed to simulate a casino blackjack gametable. Three player stations 16 are disposed on the top counter surfaceof player portion 12. Each player station 16 includes a keypad 18 and acurrency acceptor 20. Each keypad 18 includes a plurality of input keys22 by which players participate in the blackjack game. In the embodimentshown, the currency acceptor is a bill acceptor configured to receivebills of various denominations.

In this embodiment, each keypad 18 includes a first row of five, and asecond row of two, input keys 22. It should be understood by those ofordinary skill in the art that the use, number, and arrangement of suchkeys can depend upon the nature of the video gaming program operatedwithin the present invention. For example, a blackjack game may requirethe use of different keys for different purposes than a poker game. Billacceptor 20 accepts bills for betting and/or game fee purposes.

A central ticket dispenser 19 is mounted on the cabinet within reach ofall the player stations 16. Players may “cash out” at any time byinputting a proper command at their player station. Upon cashing out, aprinter 21 mounted within player portion 12 prints a redeemable ticketindicating the player's winnings via ticket dispenser 19.

Referring how to FIG. 2, keys 22 (FIG. 1) trigger compression switches24 when activated by a player. Compression switches 24 communicate viacommunication lines 30 with an interface processor such as CPU 26forming part of an interface device 28.

A compression switch 24 is triggered each time a player depresses and/orreleases its corresponding key 22, thereby sending an electrical playerinput signal, for example a pulse or a change in current, to CPU 26 overits corresponding communication line 30. CPU 26, for example an INTEL8048 device, is programmed to correlate a signal from a givencompression switch 24 with a predetermined interface signal. Forexample, upon receiving a signal from a switch 24, CPU 26 may output adigital number peculiar to that particular switch.

Additionally, each bill acceptor 20 is configured to receive papercurrency and to output a currency input signal corresponding to theamount of money input to the device. For example, bill acceptor 20 mayoutput five pulses upon receiving a five dollar bill. Bill acceptorsshould be known and understood by those of ordinary skill in the ad,and, thus, a detailed description of their operation is not providedherein.

CPU 26 also correlates the currency information to a currency outputsignal. Thus, upon receiving five pulses from a bill acceptor 20, CPU 26may output five identical digital numbers.

CPU 26 outputs the interface and currency output signals to a bufferdevice 32 for storage. In this embodiment, the interface signals andcurrency output signals are all digital numbers. It should beunderstood, however, that any suitable coding method may be employed.

Player station 16 and interface device 28 are housed in player portion12 of cabinet A (FIG. 1). A personal computer assembly 34 is housed indisplay portion 14 (FIG. 1). Personal computer assembly 34 may be apersonal computer circuit board alone, or may include various peripheralelements such as a memory device. Personal computer assembly 34 includesa series of data ports. These ports may be configured, for example, fora variety of predetermined purposes, including receiving keyboard andmouse input and outputting monitor and printer output.

Personal computer assembly 34 houses a game processor such as a CPU 38for executing a blackjack gaming program responsively to the informationinput by the players at player stations 16. An input/output system suchas a BIOS 39 receives the interface and currency output signals frombuffer 32 via a communication line 40, a keyboard port 36, and a bus 35,BIOS 39 outputs a signal to CPU 38 over a bus 41 to convey informationcarried by the interface signals and currency output signals to CPU 38.As should be understood by those of ordinary skill in the art, BIOS 39may further decode or encode signals received by CPU 26 depending upon,for example, the requirements of CPU 38 and/or the number or sequencesof activations of switches 24.

Moreover, a variety of circuitry configurations are possible within therange of personal computers. For example, a variety of input/output,memory (for example RAM 37), buses, and other devices may be arranged oncircuit board 34 in various suitable configurations. Furthermore,various methods may be employed utilizing such devices andconfigurations in communicating information between keyboard port 36 andCPU 38. It should be understood that all suitable such personal computerconfigurations may be employed in accordance with the present invention.

As it executes the video card gaming program, CPU 38 outputs videodisplay signals to a monitor 42 via a parallel port 43. The video cardgaming program executed by CPU 38 permits interactive participation by aplurality of players at player stations 16.

The video card gaming program is preferably written in an “event-driven”language such as visual Basic or Visual C. An event-driven programperforms operations responsively to “events,” such as the depression ofa push-button 22 that, in turn, causes BIOS 39 to output a signal to CPU38. For example the receipt of five signals from BIOS 39 correspondingto a particular bill acceptor 20 causes the program to add a five dollarcredit for the player at the corresponding player station 16.

Although a variety of card gaming programs may be utilized in accordancewith the present invention, in one presently preferred embodiment CPU 38is configured to execute a blackjack game wherein the gaming programgenerates a “dealer's” blackjack hand on monitor 42 that is visible tothe players at player stations 16. The players submit wagers, accept orreject card “hits”, and select game options via keys 22 at playerstations 16. The players' hands are displayed on monitor 42 along withthe dealer's hand in a manner similar to the display of cards on acasino blackjack table. Various versions of the basic blackjack or “21”game are known and may be employed in accordance with the presentinvention.

While one or more preferred embodiments of the invention have beendescribed above, it is to be understood that any and all equivalentrealizations of the present invention are included within the scope andspirit thereof. For example, communication lines from the currencyacceptors may be routed directly to one or more ports on the personalcomputer assembly, bypassing the interface assembly. This may beadvantageous, for example, if large denomination bills are frequentlyinserted to the currency acceptors. Additionally, the currency acceptorsmay be configured to accept hard and/or paper currency. Thus, theembodiments depicted are presented by way of example only and are notintended as limitations upon the present invention. Thus, whileparticular embodiments of the invention have been described and shown,it will be understood by those of ordinary skill in this art that thepresent invention is not limited thereto since many modifications can bemade. Therefore, it is contemplated that any and all such embodimentsare included in the present invention as may fall within the literal orequivalent scope of the appended claims.
